MOTOR SUPPORT FOR BOTTLE-WASHING MACHINES.

Application filed January 5, 1926. Serial No. 79,487.

This invention relates to improvements in bottle washing machines of that kind havin a plurality of revolving spindles provide with brushes which are adapted to clean the bottles while they are held by hand.

The objects of the invention are to con struct an improved and simplified machine of this type of strong and rugged construc tion having a motor drive and an improved mounting for the driving motor, which mounting is ad'ustable for the purpose of increasing the distance between the motor pulley and the driven pulley of the machine to take up the slack in the driving belt; also to provide a splash guard .of improved and simplified construction which is adapted to be connected to the motor support, and is movable therewith and also with the motor, and is adapted to surround and guard the driving belt and motor pulley and at the same time protect or shield the ventilating openings in the adjacent end of the motor against the entrance of water thrown in the direction of these parts in the use of the machine; and also to improve the construction of machines of this kind in the other respects hereinafter specified and claimed.

In the accompanying drawings,

Fig. 4 is a similar View of one of the side brackets to which the motor platform is adjustably connected.

Fig. 5 is an elevation of the machine,- partly in section, on line 5-5, Fig. '1.

The bottle washing machine illustrated in the drawings is rovided with a air ofhorizontal, space and longitudina y extending spindles 10, on which vbrushes for washing the insides of two bottles simultaneously are secured, and an intermediate, longitudinal spindle 11, which sup rts a brush for washin the outside sur aces of the two bottles w ich are being washed by.

the first mentioned brushes. The brushes are not shown in the drawings. The spindles 10 and 11 extend rearwardly through a lower splash. guard and bearing member 12 proectmg upwardly from the base plate 13of the machine, and the spindles terminate in a gear housing 14 in which are mounted suitable gears (not shown) meshin with one another and secured to the spin 'es for rotating the brushes. Motion is imparted to these gears through a pulley 15 secured to the spindle 11 outside ofthe gear housing 14, which, in turn, is driven by an electric motor 16 arranged above the gear housing 14. The motor is provided with a drive pulley 17 secured on the end of its shaft 18, said pulley being operatively connected to the pulley 15 to drive the same by a belt 19.

In accordance with the invention, the motor 16 is operatively mounted on the machine inthe following manner.

The gear housing 14 is formed with opposite side walls 20 to each of which is secured an upwardly extending supporting arm or bracket 21. Each bracket has a securing flange '22adapted to engage one of the walls 20 of the gear housing, and is provided with apertures for the reception of or securing devices 23, whereb it 1s rigidly secured to said walls 20.

extending web'31, the lower edge of whic preferably conforms approximately to the shape of the top surface of the gear housing 14. This flange is provided with apertures 32- ada ted to register with like apertures 33 in tie supporting arms 21, whereby, by passing bolts 34 through the registered apertures, the platform 28 can be secured and held firmly in place on the machine.

A belt hood and splash guard 35 is'probe flange 22 terminates at its upper end in an offset portion 24 from which an upwardl vided which is adapted to surround the motor pulley 17 and belt 19, bein formed with opposite longitudinally side flanges orwalls 36 which terminate at their upper ends in a curved wall 37 extending over the upper part of the pulley l7 and a transverse fiat wall '38 connecting. the side walls or flanges 36. This hood and guard, in addition to protecting the o rative' afiainst injury from the moving be t 1 9, is a adapted to act as a lash guard to intercept water thrown in t e direction of 10 the motor in the use of the machine, and

prevent the water from entering the annular series of ventilating apertures 38 in the adjacent end of the motor ca The ard is constructed and adapte to be rigidly secured to the motor platform 28, and for this purpose is provided with a pair of oppositely extending lateral lugs 40, preferably formed inte rally therewith and adapt- -ed to engage an be rigidly secured to cortor platform 28 is adjustable vertically rela-- ti e v y to the fixed brackets or arms 21, so that the proper tension of the driving belt may be maintained. For this purpose the registering apertures 32 and 33 in the platform 28 and supporting arms 21 respectively are preferably made in the form of verticall elongate slots, (see Fig. 2) whereby, by oosening the bolts 34, the platform 28 with the motor 16 thereon may be elevated as required torovide the necessary tension on the belt, an as the combined belt hood and splash guard 35 is rigidly secured to the platform 28, this guard 35 is always moved with the motor 16 and is maintained in correct relationto the motor ulley 17 and belt 19 without the necessity 0 separate adjustments of the guard.

The adjacent engaging faces 26 of the supporting arms, and the opposite end portions of the motor platform web 31 are preferably formed with transverse, spaced corrugations or ridges 45 and 46 respectively,

which are adapted to interfit so that, in the different adjustments of the platform on the supporting arms, slipping of the motor platform relatively to the brackets is prevented and a rigid and firm connection is insured at all times.

I claim as my invention 1. In a bottle washing machine, the combination with a frame, a spindle rotatable in said frame and having a pulley thereon, a motor having a pulley on its shaft, a belt connecting said motor pulley to said spindle pulley for rotating said spindle, of a pair of fixed spaced arms on said frame, a motor platform extending between said arms and adapted to support said motor an adjustable connection between said platform and said arms adapted to permit said motor to be positioned at different distances from said frame, whereby the belt may be maintained under proper tension, and a belt hood adapted to extend about said belt and substantially encircle said motor pulley, said hood being, rigidly connected to said motor platform, whereby said hood is movable with said platform in the adjustments thereof and is maintained in correct relation to said motor pulley and belt.

2. In a bottle washing machine, the combination witli'a frame, a spindle rotatable in said frame and having a pulley thereon, a motor having'a pulley on its shaft, a belt connecting said motor pulley to said spindle pulley for rotating said spindle, of a pair of fixed spaced arms on said frame, a motor platform extending between said arms and adapted to support s'aid' motor, an adjustable connection between said platform andv said arms adapted to permit said motor to be positioned at different distances from said frame, whereby the belt may be maintained under proper tension, and a belt hood adapted to extend about said belt and substantially encircle said motor pulley, said hood being rigidly-connected to said motor platform, whereby said hood is movable with said platform in the adjustments thereof and is maintained incorrect relation to said motor pulley and belt, said hood also being positioned adjacent one end of said motor and adapted to act as a splash guard to prevent water from being thrown, against said end of the motor.
